CHP is an abbreviation for Combined Heat and Power. It is a technology that produces electricity and thermal energy at high efficiencies. Coal units track this information in the Captive Use section when known.

Background

The equipment at the Hrazdan TPP has been deemed obsolete and inefficient, and authorities in Armenia have decided to shut down the old power plant. The plant was announced to be shut down in 2018, yet continues to operate as of September 2023 due to its role as a reserve power station.

Reported capacity of the Hrazdan TPP in 2021, excluding the combined cycle unit, was 410 MW. Two units remain operational, with others having reached the end of their lifetime. IAEA reports the capacity of the two operational units as 370 MW, while IEA reports 410 MW. Units 2-3 (200 MW) and 2-4 (210 MW) are presumed operational, while others are presumed mothballed until permanent decommissioning. According to the website of the power station, the installed capacity is 1,110 MW and the generating capacity is 760 MW.A project to rent a part of the power plant's territory to refrigerator parts manufacturing company has been approved in January 2022. Other part of the territory will be rented to cryptocurrency mining.

In 2023, as part of the liberalization program of the national electricity market, the power station was expected to increase the volume of produced electricity, which will become an important resource of energy export to Georgia.

As of September 2023, the power station is only used for power system balancing - out of two 200-MW units, mostly, one is working generating 150-160 MW (90 MW at night). The role of the power station has been decreasing over the past years, and in the future it will be replaced by a new 50-MW power unit (Hrazdan Power Station).

In December 2023, it was reported that the planned output of the power station had been significantly reduced by approximately 240 million kWh. Due to the high cost of electricity production, the plant is only activated when other power stations cannot connect to the grid or increase production. According to the plan, the Hrazdan TPP will only be operational for a few days in August.

Unit 2-5 (Razdan-5 Gas Unit)

The newest combined cycle unit (2-5), also known as Razdan-5 TPP, will continue operating.

In 2022, the Razdan-5 Gas Unit stopped for repairs, but was fully restored in 2023 having generated approximately 180 million kWh.
